Abstract

The invention discloses a helical drill pipe with dual power quick joint, which comprises a main body of the drill pipe. The main body of the drill pipe is provided with helical blades. Both ends of the main body of the drill pipe are respectively provided with a male joint and a female joint. The main body of the male joint is a hexagonal prism. , the inside of the female connector is a hexagonal hole corresponding to the male connector, the middle part of the male connector is provided with blind holes, the lock tongue is installed in the hole, and the bottom surface of the lock tongue is provided with a compression spring; the end surface of the male connector is processed with a small blind hole for installation limit Screws in order to limit the telescopic range of the lock tongue. A circular through hole is provided on the axial side of the female joint to cooperate with the lock tongue. A cylindrical groove is provided at the bottom of the female joint. The O-ring is radially sealed with the straight shaft end of the male joint; the end faces of the male joint and the female joint have a central through hole along the axial direction for the passage of high-pressure air. The drill pipe of the present invention adopts the dual power combination of wind slagging and mechanical slagging to improve the efficiency of slagging in soft coal seams, which is safe, reliable and has high working efficiency.

Description

technical field [0001] The invention relates to a helical drill pipe with dual power quick joints, which is mainly applicable to the technical field of gas drainage drilling in soft coal seams. Background technique [0002] For soft coal seams with high gas and coal and gas outbursts, gas drainage can prevent gas disasters and ensure coal mining safety. Therefore, gas drainage in coal seams is of great significance. During the extraction process, a difficult problem is the hole forming technology, which determines the extraction efficiency, timely discharges the coal dust out of the hole, and prevents the accumulation of coal particles in the hole to cause the hole to be blocked. At present, the drilling rig provides power, and the single-power mechanical slagging method of auger pipe slagging is widely used. This slagging method is very prone to problems such as drill sticking and suction, and the drilling efficiency is very low. Dual-power auger drill pipe means that the ...
